内蒙东升庙硫铁矿为特大型多金属沉积变质硫铁矿床,工业类型分单硫和锌硫两类。锌硫类型矿石为含铅、锌品位较低的硫铁矿石,伴生有银、钴、镉等有益元素。为充分回收铅、锌、硫,并尽可能将有益元素富集到精矿,以便冶炼时回收,我们进行了细磨浮选和粗磨—锌中矿再磨浮选流程的选矿试验。 Inner Mongolia Dongshengmiao pyrite is a super-large polymetallic sedimentary metamorphic pyrite deposit, and its industrial type is divided into single sulfur and zinc sulfur. Zinc sulfur type ore is lead, zinc grade pyrite, associated with silver, cobalt, cadmium and other beneficial elements. In order to fully recover the lead, zinc and sulfur, and enrich the beneficial elements to the concentrate as much as possible for recovery during smelting, we carried out the beneficiation test of the fine grinding and flotation process and the coarse grinding-zinc intermediate ore resurfacing flotation process.
